Description
Technical field
The present invention relates to railway traffics to cross the excessive phase current controlling party of split-phase technical field more particularly to a kind of flexible ground
Method and device.
Background technique
Electrification railway contact net uses single phase industrial frequence ac power supply method, in order to reduce Three-phase Power Systems power supply network
Voltage unbalance factor and raising power grid utilization rate, electric railway are using segmentation split-phase power supply, i.e., different in voltage-phase
The differential gap of a Duan Wu electricity is embedded between two supply arms, it is smoothed by overlap between each supply arm and differential gap
It crosses.In electric railway operation, in order to reduce the adverse effect of contact net electricity phase-separating section, vehicle-mounted automatic passing over of neutral section is mostly used greatly
Or ground automatic passing over of neutral section.
Vehicle-mounted automatic passing over of neutral section: after train is obtained from the mistake split-phase anticipating signal that terrestrial transmission is come, being confirmed first,
Then the trigger pulse (being equal to driver when crossing split-phase manually to return to zero traction handle) of traction convertor is blocked, delay disconnects master
Breaker makes train coasting pass through non-Electric region.After through non-Electric region, train is restarted according still further to opposite sequence.
Vehicle-mounted automatic passing over of neutral section be substantially it is a kind of powered off split-phase, power off area head, there is that certain speed loss is big, leads
Gravitation is lost seriously, and overvoltage phenomenon is serious, threatens the safe operation of electrical equipment.
Ground automatic passing over of neutral section: according to the switchtype of use, ground automatic passing over of neutral section can be divided into mechanical switch ground certainly
Moved split-phase, electronic switch ground automatic passing over of neutral section and flexible ground automatic passing over of neutral section.
Mechanical ground automatic passing over of neutral section is reached in when train passes through phase-separating section by the successive switching of two sets of switches
Property area power supply purpose, can greatly reduce in this way train without electricity time, reached reduce speed and loss of traction mesh
's.This method train speed, loss of traction.
Electronic switch ground automatic neutral-section passing system basic principle is identical as mechanical ground automatic passing over of neutral section, but uses electronics
Switch realizes the connection and disjunction of main circuit, and fast response time can accurately control switching-on phase, inhibits to close a floodgate and shove, can
To realize zero-crossing switching, overvoltage is reduced.
Flexible ground automatic passing over of neutral section uses full-control type device for power switching, realizes the controllable power supply to differential gap, realizes
Train automatic passing over of neutral section.This method takes electricity from the contact net supply arm of tractive power supply system, after over commutation and inversion link, to
The contact net of neutral section is powered.The supply conductor voltage of real-time detection train position information and two sides supply arm, according to detection signal,
To the output voltage of passing phase insulator device, using gradual adjusting voltage magnitude phase, neutral section contact net voltage is supplied from one
Electric arm contact net voltage passes through the time of multiple cycles, and the width of another supply arm contact net voltage is gradually transformed to load phase shift
Value and phase may finally realize that the flexible of train unaware crosses split-phase.
It is existing to cross in split-phase Train position detection method, due to the shunting function of each conducting wire of contact net, it is difficult contacting
Net realizes the detection of train full current, only can learn a part of train electric current (i.e. by some conducting wire of contact net
The electric current and train electric current same-phase detected, amplitude are less than train electric current).In the current control method of conventional current transformer,
Requiring controlled electric current is complete known quantity (current amplitude, phase are known), therefore temporarily soft without can be applied at this stage
The current control method of property ground automatic passing over of neutral section.

It is equal.Wherein, reference value 0, regulating time are generally 10 ~ 25ms.Which control response is fast, but is likely to occur transient state impact
Electric current, the factors such as size and main circuit structure, control strategy, control parameter are related.
Mode two: as shown in figure 4, train is denoted as t=0 at the time of driving into overlay region a, CTa electric current is I0, current reference value
For Iref=I0-t×I0/Tc(Iref>=0), t is time parameter, TcFor the current regulation period, then current reference value is in time TcIt is interior by
I0Gradually become 0.This method may be implemented after train enters overlay region a, and CTa electric current is gradually decreased as 0, can avoid transient state impact
Electric current.
In the present embodiment, for overlay region b, there are two types of modes for the control process of electric current.Mode one: as shown in figure 5, column
When vehicle drives into overlay region b, using Current Transmit b electric current as control object, its value of feedback is subtracted each other with reference value, difference is logical
Overcurrent adjuster is controlled, after certain regulating time, such as Tc, so that current sensor CTb electric current and reference value
It is equal.
Mode two: as shown in fig. 6, train is denoted as t=0 at the time of driving into overlay region b, CTb electric current is I0, current reference value
For Iref=t×I0/Tc(Iref>=0), t is time parameter, TcFor the current regulation period, then current reference value is in time Tc by 0
Gradually become I0.This method may be implemented after train enters overlay region b, and CTb electric current is gradually increased as I0, can avoid transient state impact
Electric current.
In the present embodiment, by above-mentioned control method, as shown in Figure 7 (a), train is at the end of overlay region a, train
Electric current is all provided by the electric current that passing phase insulator device is output to the neutral conductor；As shown in Figure 7 (b), at the overlay region end b, train
Electric current is all provided by supply arm b.Wherein, time T >=0.Even if being deposited in passing phase insulator device output voltage and supply arm voltage
In difference, this method can guarantee that electric current conversion process can be completed in overlay region in train, can effectively solve due to current difference
Value I and caused by chopping current problem, reduce the overvoltage as caused by chopping current, overcurrent, the hidden danger such as arcing.

When current transformer detects electric current, judge that train enters the overlay region.
9. the excessive phase current control device in flexibility ground according to claim 8, it is characterised in that: described control unit root
The current regulation period is determined according to the speed of train and the length computation of the overlay region, and the passing phase insulator device is in the electric current
Control in regulating cycle is so that the electric current that first arm is provided to train is 0.
10. the excessive phase current control device in flexibility ground according to claim 9, it is characterised in that: described control unit
By adjusting the output electric current of passing phase insulator device, so that train is when being driven out to the overlay region, by first arm to train
The detailed process that the electric current of offer is 0 include: using train enter overlay region when at the time of as initial time and record time parameter,
Using the electric current of the first arm as initial current, according to the time parameter and the initial current calculating current reference value, with excessive
The output electric current of phase device is feedback signal, using the electric current of supply arm as control object, so that the electric current of supply arm is equal to electric current
Reference value, so that train is 0 by the electric current that first arm is provided to train when being driven out to the overlay region.
